whereby the quantity of oil or other lubricating materials may be increased or di minished in a convenient manner.

- These and other' like objects are attained by the novei construction and combination or' arts hereinafter described and shown' in the accompanying drawing, forming a ymaterial part this disclosure, and in which:

Figure 1 is a fragmentary side elevational View, showing a -conrengtional type of engine cross-l1ead, and the manner in which the lubricating device is ap rlied.

Fig. 2 is a partial ,/ertic-al sectional view through the plstonoiA the engine.4

Fig'. 3 is a vertical sectional view, taken on line 3-3 of Fig. l.

Fig. et fragmentary end view of the piston, parts being brokenvaway in order to show the .firrangemcnt of lubricating parts therein. t

Fig. 5 is a vertical sectional view, taken on line 5-5 of Fig. 1, and,

Fig. 6 is a horizontal sectional view, taken on line 6-6 of Fig. l..

It is to heV understood that throughout the drawing the partsV relating specifically to the engin/cl are of conventional type of construction, and of these parts the cylinder is designated by the numeral l0, in which is mounted to operate reciprocatively a piston, comprised or a head ll and plate l2, containing the usual tapered axial opening, to

which is suited the end la of the piston rod 15, the saine beingsecurely clarnped by the nut 16, through which may bev passed asccuring pin 17.

Engaged within the head il, and held by the plate 12, are packing` rings 18, and a cenlpacking` screw 4l,

tral lulnicating;V ring lf), normally pressed outward by a spring ring 20 -as is common.y The opposite cud of the piston rod l5 held in any approved manner within a projection L2, formed with the cross-head by the tapered key 28 in a rigid manner.

The cross-head is comprised of a pair oi' .oppositely disposed curved slide elements 25, adapted to engage with the fixed guides ofthe. cugino (not shown), the central portion of the cross-head containing a recess c,

through the side walls of which is entered the wrist-pin 26held in position by the nut 27, the connecting rod 28 having an enlarged head :25) through Which the Wristpin passes.

Attached to the projection 22, is a bracket 3U having acentral projection 3l entering an opening formed in" the Vprojection so as to bc located thereby, the bracket being held by screws andextending outwardly trom the bracket is a casing' 33, having` atene end va raised hollow projection 34, normally covered by a plug 35, and through which the oil is entered into the casingor reservoir 33,

The casing is further provided at its extreme lower portion with a drain 36 normally plug-ged by the screw the opposite endand Central of the reservoir 33, is a projection 38, bored to receive a plunger 40, extending inward through the which compresses the packing 42, thc upper end of the plunger being reduced and having' iittcd upon it a hub 4i from which extends a rigid arm 4.5, the function of which will bc further on described. l

The extending end 47 of the plunger is guided in an arm 48, forn'ied with a bracketk 50, secured tio the top ot' the cylinder 38, by extending flanges 51 held by the screws 52. This bracket is essentially rectangular and provided with sides 54, in which is journalcd a spindle 55, having all'lxedupon it a worin wheel 56, driven by a worm 57, mounted in a covered casing 5S formed with the bracket 50, from which extends the arm 48, thc worin having integrally formed projecting ends 59, journalcd in the upper portion of the bracket, one of the ends extendingtherethrough and having secured upon it a ratchet wheel 60.

Engageable with `the teeth of the ratchet wheel GO is a `pawl (S2 pivoted on the pin 63 to a lever 64, journaled ony the extending -lll end 55.? and conncct ing uz. ils outer cuni Wiih :L levcr (i5, pivotully engaged with nu n 'in 66, fil-:cd upon u spindlc (33, xnountcfl in hearings transversely formed in 'che crosshead adjacent: to the upper sliding @lo mont 25.

Rigidiv engaged upon the centcr of thc spindle (5% is i; huh 69 from which elite-,nds nn arm 70, having formed through is ontor and a plurality of openings 7l, receptive of a stud 72 which passen hrough the fork M of 'n ,link 75, pivoted ut iis outer end upon n pin 76, aliixcd within the clothed hond of a sind 77, scrcw-tlucudcol into lzhc enlarged head 9.9 of the corinccting rod 28.

From the foregoing it will hc een that die connccingh rod, duc to itsy connection 'wih -i'he engine crnul. is nctuzied, motion will be transferred izo lle lever (i4, :uuhdue to iho nnwl conuecion with l'hc ratchet wheel', thoiworinwvhcel will he rotated. rzummitlzing motion to thc spindle in un obvious manner.

lf'xcrl upon the Spindle 55, beside the worm uhecl 5G. is n, Stm' wheel or com luwiug; three contacting elcmcnts or nrms 80. Also secured upon the Spindle 55. adjacent to thc sini' u'hccl 80, in u missing cum Si, having point"y 52, thc slome liciug adopted lo mnhc ionuecuirc coulecl with u projection formed with rho huh pivotcd on o piu 8f3. nail in 'lhe 'lrmuc 50, und :also formed with thc hun of; is :i 'lover arm Si, cxiending ouwnrd so us to oud-ie connut(4 Willi tho imd urn! if upon rho plunger no vhn; :is the. projccl'ioim 52 rnisc ihn element thc plunggcr olwiously will also he i'ziised due'o its engngrcnmnl, with thc. icvcr.

This :mn in cxtondcd into position lo nmlfc como :l with hc como of the ella-r u'hfwl. 1"hich obviously forces the plunger Ifl() `lo\\'uwurd into lhc horc- Fl, prcssing the oil cnmllniucd in tho res-orvoir 33. which has heen eul'crvd when ih@ plunger wu ruiscd,\
